Symfony2: 2.0 RC1 released

We will probably have a few RCs before announcing the final release but the
Symfony2 code should be fairly stable now.

The documentation has been augmented significantly with many new cookbook
entries. However, be warned that everything is not yet up to date with the
code; we will work hard on updating the documentation as soon as possible.

If you have projects that use an "old" Symfony Standard
Edition, you can upgrade to Symfony2 RC1 pretty
easily:

First, backup your project (or better, use a SCM like Git and create a new
branch)

Have you guys thought about packaging up the vendors.php script into a little script on its own? I've found it very useful so far to manage the dependencies on my Silex projects as well as keeping copies of the libraries up-to-date on disk to use in Zend Studio.
